Terrible Service!

I am very disappointed in the service I am receiving from WesBank. I have been a FNB client for 9 years and decided to do my vehicle finance with WesBank because it is a division of FNB. I recently settled my account with WesBank and some over payments were made to them. I waited a while and when nothing happened I requested a refund of the over paid funds to be made. The process has been daunting and I still have not received my refund even after promises were made! The client service is terrible as they just ignore your emails and no one ever comes back to you with feedback! I will never again finance anything through WesBank and won't advise anyone to do so either. I am also very tempted to move my personal banking to another bank!
